Analysis of vision and the situation macular edema lesions after laser treatment of diabetic retinopathy

Abstract

Objective To investigate the changes in visual acuity and macular edema lesions after laser treatment of diabetic retinopathy. Methods 92 patients with diabetic retinopathy were chosen for this study, they were treated with laser treatment,proliferative diabetic retinopathy(NPDR group)to take the whole retinal photocoagulation treatment of patients with non-proliferative diabetic retinopathy(PDR group) patients to take time full retinal photocoagulation treatment.Before and after treatment,visual acuity and macular edema changes were observed. Results Compared to pre-treatment,visual acuity after treatment in both two groups were significantly improved(0.49±0.08)°vs(0.43±0.09)°;(0.48±0.09)°vs(0.44±0.07)°],the difference was statistically significant(t= 3.728,2.104,all P 0.05);compared with before treatment,foveal retinal thickness were significantly lower after treatment[(253.41±66.73)μm vs(393.36±92.18)μm;(287.25±61.57)μm vs(388.02±89.83)μm],the difference was statistically significant(t= 6.233,3.541,all P< 0.05);the thickness of the retinal foveal in NPDR group was significantly lower than PDR group,the difference was statistically significant(t= 2.445,P< 0.05 ). Conclusion Laser in the treatment of diabetic retinopathy can significantly improve visual acuity and macular edema,and it is better in non-proliferative diabetic retinopathy,which worthy of further promotion in clinical practice.
